Summary

A method to measure dynamic J integral is developed using I integral and the numerical method of Laplace transformation. The dynamic J integral is evaluated by the developed method for an edge crack loaded by pulsatile stress on its surface in a long steel strip. Its evaluation is done using the results obtained by a dynamic FEM code and is well compared with J integral to examine the validity of the method. This method only requires the stress and the displacement time histories along the specimen contour.
